The Royal Dutch DSM Group is based on science and technology and is active in the fields of health, nutrition and materials around the world. Recently, a conductive backplane for high power back contact components has been introduced to increase the efficiency of solar modules. 3%.
This new technology benefits from the effective design of connecting adjacent cells to improve the efficiency of the module, leading to a new era of zero-loss conduction (ie, zero power loss from the battery to the module) for high-power components. Advantages of Back-to-Back Technology The electrode contacts of all solar cells are on the back, so the frontal space of the assembly is maximized, capturing light and converting it into electrical energy.
Although back-contact solar modules made of conductive backplanes have been available for many years, they have not been widely used. This is largely due to conductive backplanes (metal foils that will have a 'pattern' design combined with conventional backplanes. As a result, the function of the assembly current sink output has not yet been mass-produced at a lower cost. However, DSM today solves this problem with its original conductive backplane production process, which makes the production efficiency of the conductive backplane 100% faster than before. Times.
Back-contact solar modules can overcome traditional battery panel connection problems, reduce energy loss due to shadows, and shorten battery spacing to achieve higher power output. The design of the conductive backplane not only directs current directly into the foil layer In addition, it provides other kinds of functions, both aesthetics and design advantages.
The new conductive backplane has been planned for large-scale commercial production. Our goal is simple and clear: Let the high-power back-contact battery technology finally realize its unlimited potential.
Pascal de Sain, Vice President of DSM's Advanced Solar Energy Business Unit, said: 'This new technology is a typical example of DSM's innovation in solar energy materials to reduce the cost of standardization, reduce the dependence on fossil fuels, and make solar energy benefit the whole society. From a long-term perspective, our conductive backplanes have a wide range of application potentials in various fields. Now, we focus on commercial and residential roofs, as well as building integration solutions. Maximum power output and aesthetic appearance are indispensable considerations. . '
A solar module manufactured from a conductive backplane has been certified by TÜV North Germany and put into use in commercial components manufactured in Exasun, the Netherlands. DSM is expected to expand its customer base in Europe, Asia and North America by the end of this year.
